TABLE 2.

Overview of sleepiness and driving performance measures in the maintenance of wakefulness test (MWT) and the driving simulator (DSim) after sleep deprivation.

	MWT	DSim
MSE-L (min)	2.43 [0.97–3.36]	1.20 [0.94–6.16]
AASM-L (min)	7.75 [5.00–20.50]	60.00 [41.50–60.00]
Difference between MSE-L and AASM-L (min)	6.44 [2.17–17.51]	52.77 [38.80–58.92]
Median MSE duration (s)	4.50 [4.20–6.40]	3.40 [2.90–4.00]
MSE rate (#/min)	1.29 [0.73–1.83]	0.74 [0.48–1.59]
Cumulative MSE duration (%)	13.80 [9.35–22.53]	5.58 [3.09–12.62]
OFF-L (min)		9.57 [5.19–17.82]
Median OFF duration (s)		1.54 [1.15–2.52]
OFF rate (#/min)		1.63 [0.10–2.85]
Cumulative OFF duration (%)		4.78 [0.21–14.19]
SDLP		1463.90 [493.04–3034.65]

Data were analysed until sleep onset. Median and interquartile range are reported: latency to the first microsleep episode (MSE-L), latency to AASM-defined sleep (AASM-L), latency to the first off-road event (OFF-L), rate and duration of MSEs and off-road events (OFF), and the standard deviation of lateral position (SDLP). The cumulative duration of MSEs and OFF were calculated relative to the duration from “lights off” until AASM-L of each trial (%). Median values were first determined for each MSE or OFF per participant, and then across participants.
